The actors share three children -- Violet, 10, Seraphina, seven, and four-year-old Samuel.

"You know, we're good friends and we're doing our best and our kids are fabulous and we're working our best for them," Affleck told talk show host Ellen DeGeneres, reports eonline.com.

The 43-year-old star joked that he thinks his son will end up in "therapy" because the youngster is so convinced his new movie is real and that co-star Henry Cavill really is Superman.

"I haven't done anything that my kids can see for a long time, so I thought that would be kind of cool. My son thinks it's really cool. He came to the set, he saw me, he was a little bit suspicious. He was like, 'Is that the real Superman?' He's four so to him that's the real Superman.

"When I leave, he's like, 'Dad are you going to the Batcave?' So I'm like, 'Yes, I am.' And I know eventually he's going to be in therapy, like, 'He lied to me, there's no Batcave, he's doing Ellen!'"
